Question

Which equation is the equation of the line, in point-slope form, that has a slope of -1.8 and passes through the point (-0.5, 1.9)?


y minus 1.9 equals 1.8 open parentheses x plus 0.5 close parentheses

y minus 1.9 equals negative 1.8 open parentheses x minus 0.5 close parentheses

y minus 1.9 equals negative 1.8 open parentheses x plus 0.5 close parentheses

y minus 0.5 equals negative 1.8 open parentheses x plus 19 close parentheses

Answer 1

Slope=-1.8, X=-0.5, y=1.9
Equation is y^2-y^1=m(x^2-x^1).
Y-1.9=-1.8(X-(-0.5))
Y-1.9=-1.8x+0.90
Add 1.9 on both sides.
Y= -1.8x+1.
I hope this helps you.

Answer 2

Answer: y minus 1.9 equals negative 1.8 open parentheses x plus 0.5 close parentheses.

Step-by-step explanation:

The point slope form of a line that has slope m and passes through (a,b) is given by :-

$(y-b)=m(x-a)$

Given : Slope = -1.8 and Point  (a,b) = (-0.5, 1.9)

Then, the point-slope form of a line that has a slope of -1.8 and passes through the point (-0.5, 1.9) will be :-

$(y-1.9)=-1.8(x-(-0.5))\\\\\Rightarrow\ (y-1.9)=-1.8(x+0.5)$

Hence, the correct option is y minus 1.9 equals negative 1.8 open parentheses x plus 0.5 close parentheses.
